Subsidence can result from the collapse of underground cavities. The impact such subsidence on existing structures and infrastructures is generally dramatic. Geosynthetic reinforcement (GSY) an attractive mitigation solution that be used to reduce this impact. This paper focuses solutions over cavities mainly GSY method. A large-scale physical model (1-g) study mechanisms estimate efficacy for ...

Characterizing forces on deformable objects intruding into sand and soil requires understanding the solidand fluid-like responses of such substrates and their e ect on the state of the object. The most detailed studies of intrusion in dry granular media have revealed that interactions of fixed-shape objects during free impact (for example, cannonballs) and forced slow penetration can be describ...

Silos generally work as storage structures between supply and demand for various goods, and their structural safety has long been of interest to the civil engineering profession. This is especially true for dynamically loaded silos, e.g., in case of seismic excitation. Particularly thin-walled cylindrical silos are highly vulnerable to seismic induced pressures, which can cause critical bucklin...

In this study, we offer a general view at the area of fuzzy modeling and fuzzymodels, identify the visible development phases and elaborate on a new and promisingdirections of system modeling by introducing a concept of granular models. Granularmodels, especially granular fuzzy models constitute an important generalization of existingfuzzy models and, in contrast to the existing models, generat...

Classically used trajectory analysis models do not really account for the stochastic nature of the trajectory of falling rocks related to the variability of the impact process. The presented work focuses on the bouncing phase modelling in the case of the interaction of a boulder with a coarse granular soil. Impact simulations are first held using a Discrete Element Method. A statistical analysi...

Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...

This paper describes novel experimental methods aimed at understanding the fundamental phenomena governing the motion of lightweight vehicles on dry, granular soils. A single-wheel test rig is used to empirically investigate wheel motion under controlled wheel slip and loading conditions on sandy, dry soil. Test conditions can be designed to replicate typical field scenarios for lightweight rob...

We examine avalanche statistics of rainand vibrationdriven granular slides in miniature soil mounds using experimental and numerical approaches. A crossover from powerlaw to non power-law avalanche-size statistics is demonstrated as a generic driving rate ν is increased, due to diminishing timescale separation (∼ ν) between stress buildup and release. For slowly-driven mounds, the tail of the a...
